Numerous sites around Moore, Oklahoma are confirmed to have suffered EF-5 levels of damage, on the Enhanced (E) Fujita (F) scale. This means that the tornado that ripped through the city on May 20 was the most powerful tornado possible as its winds surged passed the 200 mph mark. On the enhanced scale the tornado’s power is not solely based on wind speed but on the damage seen after the twister has dissipated.
